Hi guys,
My unifi is facing internet disturbance for this past few days, at first thought this is just a temporary setback
The issue is it tends to disconnect & reconnect at random times, could be in few mins or after an hour and never maintained a perfect connection after an hour max
While the internet was disconnected I login to my router and I get this (refer below), but before I get to modify anything the internet reconnects again

My suspect is my router could be the problem so I switched to a spare/older router to test my theory and the exact same problem happens (both my routers are Asus brand)
I contacted unifi hotline via live chat & explained my issue & they assisted me by resetting/restarting/refreshing my unifi line from their end and instructed me to switch off my router & modem for 15 seconds
According to them this should fix the problem but nooooo, it's still happening even right now
I have 2 internet line in my home, Unifi & Maxis Fibre (via Astro IPTV)
Maxis line has no issue at all and it's currently serving as my temporary/backup line, it should be suffice for regular usage, video call/streaming but not for online gaming
So my other theory, is this because earlier this week people began to WFH and the unifi in my area is congested? Since this problem began in between monday-tuesday this week
Or could there be other factor?
Thx
